Blocked Drains Christchurch

We clear blocked sewer and stormwater drains in Christchurch using water blasting and vacuum equipment. Tell us where water is backing up and whether it has happened before so we can discuss clearing and any investigation needed.

Describe what is happening

One slow fixture, several drains backing up and water overflowing outside are different clues. Note which areas are affected, when you first noticed the problem and whether it changes during rain or when another fixture is used. Our blocked drains guide helps organise those observations.

If wastewater is overflowing, avoid adding more water through affected fixtures. Keep people and pets clear of contaminated water and tell us about the overflow when you call. Do not enter a drain or chamber to investigate.

Clearing and investigation

We use water blasting and vacuum suction equipment to clear blockages. Where further investigation is needed, our CCTV and pipeline robotic cameras help examine the inside of the drain, with GPS location supporting the investigation.

Clearing can restore flow, while inspection helps explain a persistent or recurring fault. If your drain keeps blocking, share the dates of earlier work and any findings rather than treating each event as unrelated.

Have these details ready

  • Your Christchurch address and the best number to reach you.
  • Whether the affected drain carries household wastewater or rainwater.
  • Which fixtures or outside drains are affected.
  • Whether water is contained, rising or overflowing.
  • Any previous clearing, repairs or camera inspection.
  • Access restrictions, gates, vehicles or surfaces around the suspected route.

You do not need to diagnose the cause before contacting us. Clear observations are more useful than a guess about the buried pipe.

If more than clearing is needed

When the investigation identifies damaged pipework, we can discuss repair, replacement or structural lining as appropriate to the condition. Relays can include reinstatement of concrete, hot mix, pavers and gardens.

Review our drain repairs in Christchurch page for the next stage. For budgeting, the drain unblocking cost checklist helps you ask what is included in the clearing scope and what would be additional.
